Trusted Execution Environments (TEE)s are a feature of Intel, AMD, ARM and other chip platforms, widely available on public clouds for high security infrastructure. Kubernetes can be deployed with TEE enclaves to create a Trusted Computing Base (TCB) which can cryptographically protect the compute and memory environment for the Kubernetes control plane, data flows, and CI/CD pipelines on-chip. This greatly reduces the attack "surface area" and reduces 3rd party supply chain risks. The session will examine detailed Kubernetes threat models for critical infrastructure and demonstrate how to attack and defend Kubernetes workloads in the context of TEEs. Attendees will learn how to use enclaves to protect the integrity of container images used for workloads, deploy TEE-based Pods,.examine development and operational challenges with TEE usage, and explore compliance benefits including specific policy and control mappings for GDPR, CCPA, PCI, HIPAA and NIST 800-53.
